Model Details

Multi -Channel Video/Audio Production With On-Board SD & HD I/O You can configure a K2 media client as part of a SAN solution with over 100 channels of sharing common storage— or deploy a standalone client with internal or external storage for use in a distributed environment. The Grass Valley™ K2 media server/media client system is ideal for broadcast and production environments, offering support for a wide range of applications to address specific workflow needs in the most cost-efficient and cost-effective ways possible. As a critical part of this system, K2 clients support a number of standardand high-definition (SD and HD) video formats and channel configurations (see table, third page). They also have agile playout capabilities and advanced videoplayback and audio features. You can configure a K2 client as part of a SAN solution comprised of a K2 media client, K2 media server, and K2 RAID storage—or deploy a standalone client with internal or external storage and built-in server for use in a distributed environment. Both the SAN and standalone systems are optimized to work in a file-based environment. K2 Platform – Overview The K2 platform is comprised of one or more four-channel K2 media clients connected to one or more K2 media servers and K2 RAID-protected storage. The K2 media client performs all video and audio I/O using built-in encoders and decoders. You can attach more than 100 media client channels to the K2 media servers and RAID system. For its part, the K2 media server manages the file system and controls file transfer protocol (FTP) operations. The K2 storage system offers options for internal drives or external RAID systems that can scale to more than 50 terabytes. K2 Media Client The standalone K2 media client is built around a robust computer platform with redundant hot-swappable power supplies, mirrored system drives, redundant Ethernet ports, and extra cooling as standard features. Two iSCSI or Fibre Channel ports on the client switch to provide a backup data path in case of failure, giving you a costeffective way to design a no-single-pointof- failure system. To this architecture we’ve added our Emmy® Award-winning core video technology. Built around a highperformance RISC processor and a realtime operating system, it performs video and audio processing in the robust and secure manner needed for a 24/7, frameaccurate environment. Agile Playout Capabilities You don’t always control the format of the materials you receive—but using the K2 platform, it doesn’t matter. The media client will play out any supported format back-to-back without interruption; there is no need to transcode materials into a common format. For instance, the SD media client can play DV25, MPEG I-Frame, DV50, and MPEG Long GOP materials back-to-back seamlessly.
